    Default AC condenser (rubber) tube is blocked.

    My upstairs ac unit condenser unit drainage tube is blocked. I've tried to clear it but even with 40 lbs of pressure the line will not clear. I'm looking for suggestions.

    Try connecting a shop vac to the lower side of the line.

    If that doesn't clear the line, run an electrical fish line (it's metal) to remove/push the obstruction.

    Don't run your A/C until you resolve this issue, because you don't want a leak/flood inside the house.
